    Bacteria’s Conflicts Fuel Synthetic Ecology Research

    In mixed populations of microbes, some bacteria, the "cooperators," dominate over others, the "cheaters." Cheaters use resources cooperators make and share, and the community suffers from depleted common resources. In Science, PNNL Laboratory Fellow Jim Fredrickson took on the tragedy of the commons in microbial communities. Understanding how microbes interact could help scientists design synthetic communities for use in biotechnology, turning tragedy into progress.

    Scientists Discover Precise Location of Active Sites on Popular Catalyst

    Catalysts made from oxides of vanadium, a relatively plentiful and inexpensive metal, could last longer than other catalysts and speed up manufacturing processes-especially if scientists can learn more about how they function. In this study, scientists visualized and identified the most active individual sites on the surface of supported vanadium oxide catalysts.

    Three PNNL Staff Elected to Membership in State Academy

    Jim De Yoreo, Janet Jansson and Yong Wang at Pacific Northwest National Laboratory have been selected to join the Washington State Academy of Sciences. These three scientists will join others being recognized for outstanding scientific achievement and leadership. As academy members, they will provide expert analysis to inform public policy-making, and work to increase the role and visibility of science in Washington state.

  • Scientists Hijack Light-Loving Bacteria to Make High-Value Products

    PNNL scientists have directed a common bacterium to produce more of a valuable fatty acid, lauric acid, than it typically does. The achievement is noteworthy not simply because of the increased production of fatty acid, which can be a useful component of biofuels, but it also opens the door for scientists to manipulate such organisms to produce compounds useful as fuels or medicines.

  • Marianne Sowa

    Sowa Appointed to THREE Editorial Board

    PNNL researcher Marianne Sowa was recently appointed as an associate editor for THREE (The Health Risks of Extraterrestrial Environments), a widely used, peer-reviewed, encyclopedic source of information on space radiation. It was established by NASA to provide a resource for those working in the area of space radiation research.

About The Division

Scientists within the Biological Sciences Division perform biological systems science research and develop technologies focused on how cells, cell communities, and organisms sense and respond to their environment. Our vision is to measure, predict, design, and control multi-cellular biological systems and bio-inspired solutions for energy, environment, and health.

Our investigator-initiated and multi-institutional collaborative research, unique scientific instrumentation, and national program leadership translate the latest scientific discoveries into technologies that are beneficial to the nation.

Our research has applications to energy, environment, and human health missions of the U.S. Department of Energy (DOE), the National Institutes of Health (NIH), and other federal agencies.
